Tile animations/bumps

[Grey]

I'm not too interested in proper framed animations, but I'm curious if the T-Engine can make the tiles do little hops? Like you might have the @ (or a sprite) move up 1/10th of a tile and then drop down again when hit. Or perhaps move towards a certain direction and then back again when attacking, Cardinal Quest style. Is this possible?

Would love to see animations being implemented, especially since I'm planning a realtime module .

I actually like this idea. As it stands, I sometimes have trouble telling whether or not I hit an enemy when they are in a large group, and having to repeatedly check their health and determine whether or not it decreased is a little annoying.

Tile animation support is in svn now!
Set the image to an image with all the frames left to right; set an anim property on the entity like that:
anim = {speed=1, loop=-1, max=10}

And voila!

I'll go check bumps

[darkgod]

Bumps implemented!

when you do setMoveAnim() in your actor:move code, you can add two new parameters after the blur one:
foo:setMoveAnim(ox, oy, smooth_move, blur, twitch_dir, twitch_force)

twitch_dir is one of 1/2/3/4/6/7/8/9
twitch_force is how much to twitch for (1 == one full tile)

This is easily usable to twitch attacks too; just do a move anim without moving:
self:setMoveAnim(self.x, self.y, 3, nil, util.getDir(x, y, self.x, self.y), 0.2)

You are too awesome, DG :D

Awesome! Can't wait to get anim working. It's gonna take my game to the next level.

So, I made a 640x64 image with a couple different fires that I use as walls in Hellfire.



I changed data/general/grids.lua to reflect:

newEntity{
define_as = "WALL",
name = "wall",
image="terrain/tree1.png",
display = '', color_r=160, color_g=160, color_b=160, back_color=colors.BLACK,
always_remember = true,
does_block_move = true,
can_pass = {pass_wall=1},
block_sight = true,
air_level = -20,
dig = "FLOOR",
anim = {speed=1, loop=-1, max=10},
}

I'm assuming max=10 equals ten frames? Anyways, when I try to load a new game, it never loads. I'm using the nightly build .exe, dlls from 42 and the svn code.

I didn't have the right code:

The nightly build from here:

And the dlls from 42a.

Thanks to Darkgod and _Graziel for setting me straight on IRC.

Happy animating!

After four frames (256px), I couldn't get anything to work until 16 frames (1024px). The frames would be selected off center, so the animation would slide around like looking at someone on a merry-go-round. Sometimes there would even be pieces of words that were not even in the image.

This isn't a request for it to be fixed, just a heads up to future animators. If I can't do it in 4 frames I can totally do it in 16 frames.

I bet math has something to do with why it's not working, though. Those numbers are too pretty to be coincidental.

Just got this running in my jam-based action RPG and it looks FANTASTIC! So, next challenge DG, should you choose to accept it: rotating sprites! As in you kill an enemy and it rotates and disappears. Or perhaps just does a twirl in a combat move.

[andar_b]

Another use would be to use a single tile of, let's say, grass, and rotate it 90, 180, or 270 for a little more variation. If using a true overhead tileset, walls and doors could use one tile instead of several, as well.

[tiger_eye]

Just wondering... is it possible to select the start frame for animations?

[chezzo]

Yeah, rotation would be pretty cool! I can see a lot of applications for that.

I found some more information on how many frames you can use. You can use 2, 4, 8, 16, 32, and 64 frames. And probably all the other powers of two.
